How Do Neurons Work?

The video explains how neurons transmit signals through action potentials. It covers the structure of neurons, including dendrites and axons, and how electrochemical gradients create resting potentials. The process of generating action potentials involves voltage-gated ion channels, leading to depolarization and repolarization. Neuron firing is an all-or-nothing event and is unidirectional. The myelin sheath accelerates signal transmission through saltatory conduction. The video also discusses how nerve impulses are generated in response to sensory stimuli and how the brain interprets these signals.
